Prosecutors say Schuler and another man, Austin Scott, killed the pair in their Harrison County home during a robbery in August of 2013. Both were 18 at the time of their arrest.

Court documents say the pair entered the home with the "intention of stealing items" such as guns, money and pills. Those documents went on to say that Henderson was stabbed 23 times.

Harrison County Prosecutor Otto Schalk said in November that he intends to seek life in prison without the possibility of parole for Schuler as well. Schuler pleaded guilty to beating Arnold to death. Schalk initially sought the death penalty in the case.

In court Monday, the prosecution said Schuler is beyond hope of rehabilitation and it would be unsafe for him to rejoin society. Schuler was a young adult when he took part in the murders, and the defense says he's not beyond redemption and is deserving of a second chance, so they are seeking a lesser prison term.

The prosecution should wrap up its presentation Tuesday morning. The defense will then have several days to present its information.

Scott pleaded guilty in September to avoid the death penalty. He was sentenced to life in prison, without the possibility of parole, for stabbing Henderson to death.
